It's not on my car, but on my friend's 2.0-liter VW Jetta GT with 69k easy miles.
My friend mentioned that when her husband checked the oil recently, he found some white film under the oil cap, and wondered what it was.
I went out and popped off the oil cap on the engine, and sure enough, it had this hot chocolate/cappucino tan looking foamy residue under it.
It appears the valve cover gasket is leaking, but could this be the early signs of a leaking head gasket? The foam didn't smell like anitfreeze, and no liquid or smells are coming out of the tailpipe either.
What do you think?
